v Be it 'known that I, WILLIAMDONALDSON, of Cincinnati, in the county of'Hamlton, and State of`Ohio, have invented a new and useful Improvement in Machine *for Making Beer-0aslr Bungs; and Ido ,hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled inV the art to make and use the same, reference being had to the accompanying drawings, `forming part'ot this specifi cation. v

Figure 1, Plate I, is a top or plan view of my improved4 machine.

Figure 2, Plate I, is Aa detail sectional view of the same, taken through the'line :1: a', iig'.1.Y

Figure 3, Plate II, is a detail sectional View of'th'e same, .taken through the line yy, lig. 1.

. My invention has for vits object to furnish an improved machine, `by means of which beer-Cask bungs may be formed rapidly and accurately. Y

And it consists principally in the construction,` combination, and' arrangement of the parts by which the p circular and lateral feed is eected, and of .the parts bymeans of which the timber is held steady while being operated 'upon by the knives, and released while being cut od' by the saw; the whole being constructed and arranged as hereinafter more fully described. i i

A is the frame of the machine. B isV the driving-shaft, to which motion may be given from any convenient power in the ordinary manner.- C 'is alarge pulley, placed upon the shaft B. `D is a band, passing around the pulley C and around the pulley E, placed uponthe cutter-head shaft F, to impart motion to the cutter-head G.

H is a band, passing around the pulley I, attached to the cutter-head shaftF, and around the pulley J,

attached to the saw-shaft K, to impart motion to the circular s.a\v L.` i The bearings M, of the' shafts F and K, slide upon the stationary rods or shafts N, and are rigidly com nected to eachother by the bars or framework O, so a's to be held always in thesame relative positions with respect to each other. y

The rods 'or shafts N are secured "to supports or' projectionsattached to orV formed upon the bod-plate?, which is attached to the frame A of the machine.

R is a band, passing around the small pulley S, attached to the driving-shaftl and4 around thelarge pulley T, working uponthe spindle U, attached to the frame A of the machine. V is a band, passing around the' small pulley W, rigidly connected to thepulle'y T, and working upon Ythe spindle U, and around the large i pulley X, working upon the spindle Y, attached tov-the frame Y Z is a small gear-wheel, rigidly attachedV to the' pulley X, and working upon the said spindle Y,into the teeth of which' mesh the teeth of the large gear-wheel A', attached tothe shaft 13', which revolves in bearings attached to the frame A. 4

C' is a guiding-clutcli, to hold the timbe'rand feed it fonward.

The clutch G'v is made in`the form of two half cylinders fitted' together, and having a square hole formed i longitudinally through its centre. The clutch C revolves in. bearings attached to the frame A, and has a gearwheel, D', attached to its outer end, the teeth of which mesh into the teeth of the gear-wheel A'.

E represents a square stick of timber, from which the bungs lare formed, which passes through the square hole through the clutch C. Y

F' is a block, which slides back and forth in a. recess formed in the clutch C', and which has a pin, f', formed upon or attached to it, which passes out through. a. longitudinal slot inthe side of said clutch, as shown in iig. 3.

To the sides of the block E' are pivot-ed two claws or pawls, Gr', which are held down against the timber E' by the spring II' attached tothe block F', and pressing against the claws G.

n I' are claws or pawls, pivoted `in arecess in the forward part of the clutch C', and which are held down against the timber E' bye. spring, J', to hold it while the claws'G' are being drawn back.` i

Toithe forward end of the shaft B'is attached a" circular disk or plate K', having an eccentric or cimigroove, I c', formed in its side, as shown in fig. 2, in which groove works o guide-pin, attached to the arin'L, the* upper end of which is attached to or forms a part of the framework O, so as to move the said framework, together, with thccutters aiid saw, forward and back, as the said guide-pins move along the eccentric-groove c'. M' is a centre, for supporting the end of the timber E' while revolving and while being operated upon by the eut-ters. l

4The centre M' slides in supports/attached to the bed-plate P, and is moved back and forth to grasp and release the timber'E', at the proper times, by a pin projecting from its under side, which entcrsan inclined slot formedin the plate N', which is adjustably attached to the 'framework O, :is shown in figs. l and 2.

O' are the cutters, which are adjustably attached to the cutter-head G, and which are made in substantially the formshown in the drawings, the longer edge forming the convex tapering sides of the bung, and the shorter edge sm'oothing o` the end of the timber which forms the head of the next hung. P' are serrated cutters,

adjustably attached to the cutter-head G, between the cutters O', and are so placed as to enter the timber at the point wherethe angular part of said cutters O'will enter land forni a cut or groove in advance of said cutters, to prevent the timber from being splinter'ed or torn by the action of the angular partof said cutters O.

- R' is a cam, attached to the shaft B', which strikes against an arm, s1, formedupon the under side of the inclined guide-plate S', wichis pivoted to the frame A by means of the arm s2, andwhich is made to move up and down in a vertical line by the guide-pin s3, the head of which works in a groove formed in the, edge of the bearing of the clutch C'. p l

The timberE' is fed forward by the guide-plate S' being raised at the proper time by the cam R, so that,

as the clutch revolves, the pin f' may strike'against und be forced forwardby the inclined edge oi' the said guide-plate S'.

The pin j" is'forced back, carrying thc block F and'claws G' with it, by the pin f entering theinclined groove s, formed in or attached to the said guide-plate S'. i I v The timber E' is fed `forward while the saw L is being moved back by the action of the eccentric-groove la', afterhavng ent oit the completed bung, and before the action of the said eccentric-groove has brought the cutters O' into working position. l

I claim as new, and desire to secure by Letters Patentm v i 1. The combination of the cam R', pivoted guide-plate S', pin f', block F', claws G', spring H'fpawls or claws I', spring J', and cylindrical clutch C with each other, substantially as herein shown and described, and for the purpose set forth.

2. Thegcombination of the centre M' and adjustable slotted plate N' with eachother and with the cylindrical clutch C', as 'herein shown and described, for the purpose specified.

' W. DONALDSON.
